CEMENT-FORMING APPARATUS.

To all whom it may concern Be it known that I, ADAM DzrEiIIAN a subject of the Czar of Russia, residing at Jersey City, in the county of Hudson and Referring tothe accompanying drawings,v vI have illustrated in perspective partly.'

broken away an application of. my invention.`

2, 3 and 4 represent the girders supporting the floor of a modern building, and 5 and 6 indicates the bottom of the mold surrounding the ,efirders for holding the concrete in place. These are provided with brackets such as 7 through which pins such as 8 project and rest upon the flanges of the I-beams. The pins 8. rest upon the pins 9 which may be introduced in any of the holes 10 thus making the mold adapted for diferent sizes of beams. ll is another bracket suitably secured to the lower parts 6- of the mold and provided with standards such as l2 which may be adjustably secured therein by suitable means such as 13. I The upper parts 14 ofthe molds are slidably adjustable as shown. A

15 and l6'are adjustable telescopical bars adapted to seat within the standards 12 and provided upon the upper faee with suitable points or pins such as 17. These extend at intervals between the molds as shown and serve to support suitable planking such as 1S.

19 are telesc'opical bars adapted to engage the bars 15 and 16 to hold the same in position and also serve to provide support for additional reinforcement such as the plank 9.0. 21 and 22 are also adjustable telescopical connecting bars adapted to connect the Specification of Letters Patent.

Patented Oct. 13, 1914'. Serial No. 672,659.

brackets 11 mounted upon the lower portions of the molds 5 and 6.

. From this it will be seen that the apparatus may be fitted to'beams of any size and of any separation being adjustable as aforesaid. After the apparatus is in position the planking is thrown across the supports 15, 16 and Q0 and the cement with suitable repinforcing material is spread over the entire -surface and around the beams withm the molds and after the same has set, the molds may be shifted thus leaving the concr'ete flooring in posltion.

Of course it will be understoodthat other l neans may be employed for adjusting and supportingthe molds in position and various modifications may be made without departing from the spirit of the invention as set forth in the claims :U

, I claim.

1. A molding apparatus for floors com-l prising channel shaped molds vadapted to be adjusted around the floor beams, adjustable brackets carried by the sides of said channel shaped molds, transverse supports adapted .to be supported by the brackets, and means 'located between the supports in combination with the brackets to brace said supports in lines parallel withl said channel shaped mold.

2. A' moldingapparatus for floors comprising channel shaped molds adapted'to be adjusted around the floor beams, adjustable brackets carried by the sides of said channel shaped molds, transverse supports adapted to be supported by the brackets, and means located between the supports in combination with the `brackets to brace said supports in Alines parallel vwith said channel shaped mold, .said transverse supports comprising slidable sections adapted to be engaged against the adjacent walls of adjacent molds.

In testimony whereof Iafiix my signature in presence of two witnesses.
